nCubeGrp and its child nodes
Description
A group of nCubes that may share a common subject, arise from the interpretation of a single question, or are linked by some other factor. This element makes it possible to identify all nCubes derived from a simple presentation table, and to provide the original table title and universe, as well as reference the source. Specific nesting patterns can be described using the attribute nCubeGrp. nCube groups are also created this way in order to permit nCubes to belong to multiple groups, including multiple subject groups, without causing overlapping groups. nCubes that are linked by the same use of the same variable need not be identified by an nCubeGrp element because they are already linked by a common variable element. Note that as a result of the strict sequencing required by XML, all nCube Groups must be marked up before the Variable element is opened. That is, the mark-up author cannot mark up a nCube Group, then mark up its constituent nCubes, then mark up another nCube Group. More information on these elements, especially their allowed attributes, can be found in the references.
